I am getting lot of deadlocks in my application. As it is very complex
ti avoid deadlocks at this stage of application we have done few steps
to lessen the impact.
We have added retries after deadlock is capturted.
We have added select * from TABLE with (nolock) wherever possible.
But interestingly second step is not working. I have few simple select
statements where i am using nolock criteria still I am getting
deadlock victim error....

Hi
I'm having a problem with deadlocks in a table in SQL server when
trying to update it through Biztalk 2004. There is no problem when I
use the same Biztalk solution to update a similar dummy table, but
when I try updating the original table in the production database,
some transactions are updated successfully whereas others become the
victim of the deadlock (Transaction (Process ID 185) was deadlocked on
lock resources with another...

We've found deadlocks in the trace file that were not captured by our
Powerbuilder application. Some deadlocks are trapped or, at least,
reported to the user as a db error, and others are completely silent.
We've also seen evidence of strange data that would be explained by
unprocessed deadlocks, although we've not yet proven that the
unreported deadlocks are killing updates to the db.
Putting a raiserror into various parts of the same...

We're experiencing a large number of deadlocks since we began running
SQL Server 2000 Enterprise Edition SP3 on a Dell 6650 with hyper
threading intel processors. We don't have the same problem on Dell
6650's w/o the hyper threading. If I turn off the parallel query
processing option the deadlocks stop. I've tried all of the suggestions
from the Microsoft Knowledge Base under the following link -

Hello all,
I am trying to figure out when it is appropriate to use shared and
exclusive locks with InnoDB. Using shared locks (lock in share mode), I
can easily create a scenario with 2 clients that deadlocks - start 2
transactions, open 2 shared locks, and both try to insert a new row
before either commits.
Using exclusive locks (for update) I cannot come up with a scenario that
results in a deadlock, since the very nature of the...

Hello,
We currently are running a CRM application that uses DB/2 7.2 for the data
repository. We will be upgrading to 8.2 later this year....maybe....time and
resources permitting.
The database is currently being hosted with a managed service provider (MSP)
at a remote datacenter. This service provider is supposed to be monitoring
the health and performance of the database as well as performing proactive
maintenance on a regularly...

I am running into an issue. Recently I installed IBuySpy Portal and then converted the data source to odp.net. When debugging the app my machine would freeze or become really slow. I can reproduce it by:
Setting a breakpoint somewhere in the code, hitting F5, once the application has completely loaded hit the stop button, make a quick change and then select F5 again.
It appears that the debugger attaches to the previous aspnet_wp.exe...

There's another poster complaining about referential integrity checks causing
deadlocks. Unfortunately I've deleted the message so this response (and the
archives aren't responding) isn't going to show up on the right thread.
The reason the deadlock is happening is because of a known deficiency in
Postgres that postgres has to take an exclusive lock on the records to ensure
they aren't deleted before your insert/update commits....

We're getting numerous deadlocks in a multi-user system where users are coming in and updating their own data.
In our troubleshooting/traces, the deadlocks seem to be coming from lock contention on a Primary Key Clustered Index, not on the table itself.
Also, from what we can see, the application is requesting multiple locks on the Primary Key Index as it proceeds to perform the update on the primary table.
Can anybody shed some light...

There are many references to deadlock handlers that retry the
transaction automatically.
But IMO a deadlock is the result of a design flaw that should be
fixed.
My applications treat deadlocks like any other runtime error - they
are logged and fixed.
There seems to be a an opinion that deadlocks are inevitable !

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
